6 Claims.

This invention has reference to a wringer and wringer head. mechanism and particularly to the controls thereof.

The main object of the invention is to provide easy and convenient controls for all the wringer functions and to interlock these controls to make the wringer operation safer than the conventional wringer.

Another object is to provide a clutching mechanlsm operated by release movements, of the wringer mechanism the same having operative connection with a manual control element whereby rotation of the wringer rolls may be started or stopped by manipulation of manual control means, or automatically stopped by release movement.

Another object is to provide co-operative connection between the clutching mechanism and. wringer post locking devices whereby when the post lock devices are operated to permit swinging movement of the wringer, rotation of the rolls is automatically stopped.

A further object is to provide an arrangement of mechanism whereby when rotation of the wringer rolls is stopped by means of release movement it can not again be started by manual means until after the roll pressure mechanism has been reset.

An additional object is to provide that when rotation of the rolls is stopped by means of unlocking of the post lock, manipulation of the manual control means is required to bring about resumption of rotation.

Additional objects will be set forth in the following description and accompanying'drawings in which;

Fig. 1 is a fragmental, sectional, side elevational view of a wringer head mechanism showing an embodiment of my invention;

Fig. 2 is a view similar to Fig. 1 showing several parts in operated position as will be referred to;

Fig. 3 is a view similar to Fig. 1 showing additional parts in operated position, also to be referred to;

Fig. 4 is an end elevational view taken from line 4-4 in Fig. 1 and Fig. 5 is a plan view taken from line 5-5 in Fig. 4.

Fig. 1 discloses the mechanism as generally comprising a wringer post III which carries a flanged collar H and which is adapted to rotatably support a wringer head structure l2.

The flanged portion of collar l I is provided with a series of openings l3, so disposed as to align with a pin member II which is slidably supported Serial No. 748,275

in head structure l2 and urged to enter openings l3 by a spring I5. It will be obvious that with pin l4 engaged in an opening l3 as in Fig. 1 the wringer head is securely locked against rotation upon post l0, whereas with the pin in raised position as in Fig. 2 the head may be freely rotated.

This feature will be referred to later.

Rotatably supported in structure I2 is a vertical shaft [6 to which a bevel gear I! is secured.

Gearcllmeshes with dual oppositely disposed gears l8 and I9. Shaft lower end with a It has connection at its power source, not here shown,

by means of which the shaft and gears mentioned are continuously Gears l8 and I9 have rotated. I

their hubs journalled in structure l2 by means of which they are rotatably supported and adapted to floating shaft 20, the end of toward the roll assembly for a purpose described.

A toothed rotatably support a which extends to be clutch member 2|, having a conbout its periphery is slidably mounted in keyed relation upon shaft 20 between gears of either of the gears l8 and I9 and the teeth of the teeth 23 direction or to remain in central neutral position as shown in Fig. 1.

A stub shaft tion of structure l2 and is 24 is journalled in the upper porprovided at its upper end with a handle assembly 25 by means of which it may be rotated. The

lower end of the shaft is provided with an eccentrically disposed stud 26 extending into gro A roller 21,- mounted on sides of the groove and is ove 22 of clutch-2|.

the stud, engages the thus effective, when handle 25 is rotated, to move the clutch into engagement with one of gears H! or l9 to bring about rotation of shaft 20 in selected rotation,

or to retain the clutch in neutral position.

A ball 28,

mounted in structure I! is urged by disposed indentations in the head portion of handle 25 whereby shaft 24 and clutch position.

retained in selected Fragmental portions of a roll wringer structure are shown in the several views. Since-this structure is not an important will not be described 30 designates a. lower frame, 3! an upright block 34 and the upper means of a bearing block part of further than to say that portion of the wringer portion of 32 a movable top portion thereof. is supported in upright 3| by means roll 35 is supported by my invention, it

the same and A lower roll 33 of a bearing 36 which is slidably mounted in the upright. A tensioning spring 31, supported in frame portion 32, forces bearing block 36 downwardly with the result that roll 35 is resiliently held in pressure relation with lower Frame portion 32 is shown as held in position upon upright 3| by means of an arm member 38 which is pivotally supported at 39 upon upright 3|. The arm is fashioned to have a hook portion 90 extending around the upper side of frame portion 32, and the hook is provided with an upstanding lip portion 4|. Lip M is engaged by a complemental hook portion 92 of a latch member 43. Member 43 is pivotally mounted at 44 on frame 32 and has a backwardly extending portion 45 by means of which it may be manipulated.

With the parts in position shown in Fig. 1, the arm 38, retained by latch 43, is obviously effective to retain frame 32 against upward movement, which movement would normally be produced by action of spring 31 abutting the bearing 36.

Fig. 3 illustrates the movement of frame 32 resulting from releasement of arm 38 as brought about by manipulation of latch member 43.

Fig. 3 also more clearly discloses a link member 46 pivotally attached at 41 to frame 32 and extending downwardly within upright 3|.

Secured upon link 416 is a lug l8 and disposed in the path of this lug is a forked extending portion 49 of a lever 50. The opposite leg of the forked extending portion is set back somewhat as shown in Fig. 3, and has an extending outwardly directed portion 49, the purpose of which will be described.

Lever 50 is pivotally supported at 5| upon structure l2 and has a forked portion 52 extending upon either side of a plunger member 53.

Plunger 53 is slidably supported in structure l2 as shown, and is provided with a groove 56 which is adapted to engage a ball Fig. 4, propelled by a spring 56, both retained in a cavity in structure l2. The ball is obviously adapted to temporarily retain plunger 53 in a predetermined position as will be noted later. A knob 53' facilitates manipulation of the plunger.

A coil spring 5! reacts between structure l2 and lever 50 to urge the same toward the operated position shown in Fig. 3.

Reference has already been made to a pin member l4 adapted to lock the wringer head upon post In.

The pin is manually operated by means of an extending arm 58 engaging a cross pin 59 secured in member I 4. Arm 58 is secured upon a transverse shaft 60 which latter is journalled in structure l2.

A handle member BI is secured to an extending end of shaft 60 by means of which the arm 58 is moved to bring about the described movement of pin [4.

An arm 52 is also secured to shaft 60 and carries a lug 63 which engages in a slot 64 formed in the lower end of a link 65 which extends upwardly and has its upper end supported by a shouldered portion of plunger 53.

A nut or collar 66, secured to the plunger, confines link 65 and also forms a head adapted to engage an arm of a lever member 61 which is pivoted at 5| and has downwardly extending arms 68 carrying inwardly disposed lugs 69.

Lugs 69 are engaged in a groove 10 formed about the periphery of a clutch collar 1| whereby pivotal movement of lever 51 is effective to bring about lateral movement of the collar.

' The collar is slidably and rotatably supported upon a coupling member 12 which is rotatably supported upon the extending end of floating shaft 20 and has driving connection with the shaft of lower roll 33.

Coupling 12 is provided with a circular opening 13 in its side wall in which a ball 14 is disposed and shaft 29 is provided with a longitudinal groove 15 adapted to receive the ball when in register therewith.

A coil spring 16 normally urges clutch collar H toward the left as viewed in Fig. l.

The collar, when in left hand position, is adapted to cover the opening 13 whereby the ball is prevented from escaping from groove 15. With parts in this position, the ball forms a driving connection between shaft 20 and coupling 1|.

Movement of the collar to the right, as in Fig. 2 uncovers the opening 13 which permits ball 14 to move outwardly and thus remove the connection between the coupling and shaft 2|]. With parts so arranged; shaft 20 may rotate freely within coupling H.

Operation of the described mechanism may be described as follows:

In Fig. 1 all parts are shown in normal position for operating the wringer rolls in a direction determined by manipulation of handle 25, with the wringer locked to its supporting post by pin M and clutch collar H in position to effect coupling between shaft 20 and roll 33.

With the parts in this position, plunger 53 may be manipulated downwardly to press its head 66 against lever 67 to move the clutch collar toward the right as in Pg. 3 or upwardly to perto effect driving connection as described. By the above means the wringer may be operated under conditions of ordinary use.

When conditions make it necessary to release the top frame 32 it assumes approximately the position shown in Fig. 3 wherein link 36 has been elevated, carrying lug 48 upwardly to rotate lever 50 to depress extension 52 against link 65 and through this and head 66 to move lever 61 in such a manner as to propel clutch collar 1| toward the right and thereby uncouple the driving mechanism.

It will be noted that plunger 53 has been depressed during the movements described and that the groove 54 is thus brought into alignment with ball 55 whereby the plunger is temporarily retained in depressed position.

The foregoing will illustrate the manner in which release of the top frame automatically brings about de-clutching of the wringer driving means, The driving means will obviously remain de-clutched after the-top frame is replaced, as indicated in Fig. 2. The replacing movement places lug 48 in operative engagement with fork 49 to rotate lever 50 into original position, leaving plunger 53 in lowered position, available for normal operation as already explained. It is to be noted that with parts in position shown in Fig. 3, manipulation of plunger 53, to start rotation of the rolls, is prevented by reason of the lug 48 lying opposite extension 49' of lever 50. Obviously, plunger 53 cannot be moved upwardly without rotating lever 50 in clockwise direction and this is made impossible by abutment of portion 49' upon lug 48. In this manner rotation of the rolls is automatically prevented when the parts are not in position for practical use.

An additional de-clutching means is provided in connection with the post-lock mechanism as follows;

When it is desired to swing the wringer upon its post the handle 6| is moved upwardly as in Fig. 3. This movement is effective to withdraw pin it out of engagement with collar H as shown and also, through arm 62, to move link 65 downwardly to operate the clutch as already described.

Fig. 3 illustrates that driving connection cannot be established while-handle BI is in elevated position, but that, by means of the slot 64 the handle may be placed in looking position without operating the clutch into driving position.

In view of the foregoing it is thought apparent that mydriving mechanism is adapted to operate in such a manner that releasement of the roll pressure means or unlocking of the wringer head automatically stops the wringer rolls whereby the wringer may be usedwith maximum safety, The safety feature is enhanced by the peculiar mechanical arrangement which prevents driving connection of the rolls when the parts are not in suitable position for normal use.

What I claim is:

1. A wringer head mechanism comprising, means for driving the wringer rolls, clutching means disposed between the driving means and said rolls, mechanism for releasing pressure between the wringer rolls, a wringer post rotatably supporting the wringer head, mechanism for locking the head relative to the post, and mechanism inter-connecting the locking means,- the releasing mechanism and said clutching means whereby release movements of the releasing mechanism or unlocking movement of the looking mechanism brings about operation of the clutching means to stop the wringer rolls.

A device of the class described including in combination a wringer head mechanism, wringer rolls driven thereby,'pressure mechanism for the rolls, a release device releasing pressure on the rolls, a part to be moved as a result of such release, a clutching mechanism disposed between said wringer head mechanism and rolls, a post locking mechanism, a manually operable mechanism capable of operating said clutching-mechanism to control rotation of the mechanism co-operative between the post 1ock ing mechanism, said part to be moved and said manually operable mechanism whereby said clutching mechanism may be operated to stop the rolls by means of movement of said released part, movement of said post locking mechanism into unlocked position or said manually operable member severally.

4. A device as set forth in several mentioned mechanisms are capable of operating said clutching mechanism to stop the wringer rolls as described, but wherein the clutching mechanism may be operated to start the rolls exclusively by said manually operable mechanism.

5. A device of the class described including a support post, a wringer mechanism rotatably supported thereon, mechanism for locking the mechclaim 3 wherein the wringer rolls and anism on the post, wringer rolls, pressure means therefor, release mechanism releasing the pressure means, driving mechanism for the rolls, a clutch between the driving means and rolls, a first means for operating the clutch comprising a connection between said locking mechanism automatically operating said clutch to stop the rolls when the locking mechanism is unlocked, and a second means comprising connection between the releasing mechanism and clutch automatically operating the clutch to stop the rolls when the same are released, said locking mechanism and said releasing mechanism being interconnected for operation of one of the mechanisms upon operation of the other mechanism.

6. In a wringer head mechanism for driving and controlling the rotation of the wringer rolls, a wringer head and wringer rotatably mounted on the wringer post, a manually operable lever for stopping or starting rotation of the rolls, a second manually operable lever for controlling the lock positioning the wringer rotatably on the wringer post, a third manually operable lever for locking or releasing the wringer head and wringer rolls in relation to a wringer post, and an interlocking mechanism connecting these several controls which prevents rotation of the rolls when the wringer is unlocked or open, or when the head is unlocked on the wringer post.
